Habitat & Geographic Range

Cheetah

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical grasslands and savannas, and flooded grasslands and savannas, among 9 distinct biome types spanning the Afrotropic and Palearctic realms. Populations are also found in montane and highland environments at higher elevations.

Range

Distributed across Botswana, Iran, Kenya, Namibia, and Tanzania. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Common Quaking Grass

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, temperate grasslands and steppes, and flooded grasslands and savannas, among 6 distinct biome types. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Asia (Japan), Europe (7 countries), North America (Canada, United States), and South America (Argentina). Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Cheetah

猎豹是地球上奔跑最快的陆地动物，在非洲和伊朗草原上短距离冲刺速度可达112千米/小时。体型纤细，胸深腿长，具有标志性的黑色泪纹。与其他大型猫科动物不同，猎豹以吱鸣声和咕噜声交流。由于栖息地碎片化和与更大型捕食者的竞争，猎豹被列为易危，野外仅剩约7,000只。

Common Quaking Grass

The Common Quaking Grass, <em>Briza media</em>, is a perennial grass in the family Poaceae, native to Europe and parts of Asia and introduced to North America and South America. It is a characteristic species of ancient, species-rich calcareous grasslands, meadows, and chalk downlands, where it typically grows in well-drained, nutrient-poor soils in full sun. The species is easily recognized by its heart-shaped, flattened spikelets that hang on delicate, hair-like stalks and tremble in the slightest breeze, producing the distinctive quaking motion that gives the genus its common name. The spikelets are typically pale green when immature, turning golden-brown as they ripen, and the whole inflorescence is highly ornamental. <em>Briza media</em> is an important component of calcareous grassland communities, providing structure and seed resources for invertebrates and birds. It is sensitive to agricultural improvement and is often used as an indicator of long-undisturbed grasslands. The species is assessed as Vulnerable on the IUCN Red List, reflecting declines linked to habitat loss, agricultural intensification, and conversion of traditional grasslands. Biological traits such as average lifespan, body size, and specific dietary preferences remain poorly documented for this species.
